To all whom "it may concern:

Be it known that I, ROBERT LAING, subject of Great Britain, residing atRadcliffe, Lancashire, England, have invented new and usefulImprovements in Machines for Press ing Lines or Designs intov Rollers,of which the following is a specification.

This invention relates to improvements in machines for pressing lines ordesigns into rollers used for imparting a luster or silky appearance tocotton fabrics, known as the Schreiner process.

Hitherto this type of machine had only one mill and the said lines ordesigns being pressed into the roller gradually, that is to say, therequired depth or correct form of the impression not being attainable byone run of the mill, the mill had to be run a number of times overthesame impression which rendered the operation exceedingly slow andexpensive.

The object of my invention is to provide means whereby a number of thesaid mills can be used simultaneously and the desired lines or designsthereby pressed into the roller in at least half the time than hithertohas been possible, thus saving a great deal of labor and consequentlycheapening the operation considerably. I attain these objects by themeans illustrated in the accompanying drawings, in which- Figure 1 is anend view, Fig. 2 a plan, and Fig. 3 a front view of a mill headconstructed in accordance with my invention of a machine for pressinglines or designs into rollers. Fig. 4 is a vertical section and Fig. 5 asectional plan of a portion thereof on an enlarged scale.

Similar letters refer to similar parts throughout the several views.

In carrying out my invention and referring to the figures generally, topermit of employing a number of mills a on one head I), I form the millholder 0 and pressure lever d of each mill separate from and to actindependently of each other. For this purpose I fulcrum to the shaft 6on the mill head stand f which latter travels along the work in theusual way, a frame g adapted to rest upon the mill head b and capable ofbeing raised. In the free end of this frame I mount vertical bushes h innumber equal to the number of mills a to be employed, say as in thepresent instance, three. In each of these bushes is mounted the holder 0having at its lower end a shoulder i and an open bearing 76 to receivethe mill a and at its upper end is secured a collar Z, see moreparticularly lligs. 4 & 5. The said holder is prevented from turning inthe bush h, say by a key m engaging the same, but capable of verticalmovement and normally held against the buslrh by means of a spring orsprings 72. By preference I employ three of these springs between thecollar Z and the bush h each around a pin 0 screwed into the top of thebush h and its free end passing through a hole in the collar 1.

The bush 7), has a shoulder at its top to rest upon the frame g and. bya set screw p is rendered rota'rily adjustable to permit of setting themill a at any required angle to the work q.

On the top of each mill holder 0 rests the pressure lever (1 preferablyfulcrumed to the shaft e, one in the middle and one at each end thereof,cap able of being raised independently of the mill frame g, and eachother. The

frame 9 carrying all the mill holders 0, all the mills a travel togetheralong the work 9..

In starting the work, the leading mill is brought first into operation.When the second holder has arrived at the beginning of the work, thesecond mill is brought into operation, that is to say, placed into theimpression made by the first mill and in the same manner afterwards thethird mill.

It will thus be seen that each mill works entirely independent of theother that is to say, the mill holders 0 being independently of eachother vertically movable and each having its own weighted lever, thepressure required for each mill can be successively increased at willwhich permits of having a number-of mills simultaneously working.

It is obvious that in some cases it may be found practical to employonly two or more than three mills a which latter can be readily done bycorrespondingly lengthening the mill head shaft 0 and frame g.

I claim: I

1. In a machine for pressing lines and designs into rollers of thecharacter described, a mill head, a frame fulcrumed thereto, a number ofmills individually vertically movable in the said frame and a pressurelever for each of the said mills, all combined substantially as and forthe purpose set forth.

2. In a machine for pressing lines and designs into rollers of thecharacter described, a mill head, a frame fulcrumed thereto, a number ofmill holders individually vertically movable in the said frame, apressure lever for each of and means for the rotary adjustment of saidholders, all combined substantially as and for the purpose set forth.

3. In a machine for pressing lines and designs into rollers of thecharacter described, a mill head, a frame fulcrumed thereto, a number ofindividually vertically movable mill holders and a bush around each inthe said frame, a pressure lever for each of and springs supporting thesaid holders, means for preventing the'rotation of the said. holder inthe'said bush and means for the rotary adjustment of the said bush inthe said frame, all combined substantially as and for the purpose setforth.

In testimony whereof I have signed my name to this specification in thepresence of two subscribing Witnesses.
